You would need something like this

There are cheaper diy ways but I find this works great for me.

yikes, nah don't go buying anything like that, all you need is a 10-12v wall-wart, most people have atleast 1 laying around somewhere, cut off the connector and wire up the fan and a switch of your preference.
I just asked this the other day.

You probably already have a power source laying around from an old cell phone charger or DC appliance. All it takes is a small AC/DC power adapter with about 250-500 mA power. Cut the DC plug off and splice the two wires to the red and black wires on the fans, ignore the yellow wire as it will not be needed.
The advantage to the variable voltage type someone mentioned is you can vary the fan speed, cooling effect and noise they produce by lowering the voltage. You can get a variable voltage power supply at Wal Mart for about $10 that will power 3 or 4 fans.

The back is open. Do i need fans on both ends?

Old cell phone chargers are typically 12 VDC. You can use one of those to power the fans after cutting off the end.
Fans on both ends would be fine -- I've seen some have one blowing in and one blowing out. But given your back is open, the number of fans depends on how much air your fans move and how much evaporative cooling you need.

I would put one in each end blowing in so air travels the complete distance from side to side. With the back open it is not as big a deal but with an enclosed canopy having one blw in and one blow out defeats the purpose of having two fans since the out just moves the very same air the in fed to it.
I prefer an enclosed canopy so light is contained better, its irritating trying to watch television when it looks like an arc welder in the room. I have a fan in each end blowing in and holes in the very top of the lid directly over the reflectors so light does not escape but heat does, it also takes advantage of convection and works even when the fans are not running since hot air rises.

I put mine in the lid of the canopy. Because my back was open as well I was worried about the salty humid air circulating back and going through the fans and ruining them in a short period of time. I had them blowing in the lid and it worked great. It dropped my tank 3-4 degrees.
